Species composition and diversity of tree species were analysed in 10 respresentative forest sites occurring in Sagar District (Madhya Pradesh). As per values of IVI (Importance Value Index) six forest communities were identified. In general the forest vegetation of the district is either teak (Tectona grandis) dominating or teak associated. Species richness and species richness index ranged from 18 to 50 and 1.120 to 2.343 respectively. Shannon-Wiener diversity index ranged between 2.22-3.66 and Beta diversity ranged between 0.69-1.83. The values of concentration of dominance were generally low at all study sites indicating the dominance is shared by more than one and/or many species. Dominance-diversity curves showed log-normal distribution, also indicative of shared resources pattern by a number of species and mixed nature of vegetation.Keywords

An experiment was conducted to observe the studies on the major insect pests of okra during Kharif season of 2011 at Department Of Entomology, Live Stock Farm, Adhartal, J.N.K.V.V. Jabalpur (M.P.). Jassids and whitefly incidence was observed from 27 DAS (16 September 2011) to 90 DAS (18 November 2011) with one distinct peak, respectively during 44 SMW withmean population (nymph + adult) per 30 leaf was 26.11 for jassids and 25.6 for whitefly. While initation of fruit infestation by shoot and fruit borer recorded at 41% SMW (01-07 Oct 2011) and epidemic at 41SMW (08-14 Oct. 2011) with 35.35 per cent.Keywords

Field experiments were conducted during Kharif 2011 to evaluate the efficacy of six insecticides against sucking insect pest jassids (Amrasca biguttula biguttula) on okra (Abelmoschus esculentus L.). Spraying of difenthiuron 50 WP @ 300 g a.i./ha was found significantly more effective and the next treatment Thiamethoxam 25 WG @ 25 g a.i./ha was also significantly effective in controlling jassid population.Keywords
